PROPOSALS ON COOPERATION IN THE SPHERE OF LV SYSTEMS, SUBSYSTEMS AND COMPONENTS DEVELOPMENT

The PCCS system is intended for optimization of the propellants' operative reserve application during the flight as well as for definition of the time of this reserve termination.


PROPELLANT-CONSUMPTION CONTROLSYSTEM (PCCS)

 

The PCCS system is intended for optimization of the propellants' operative reserve application during the flight as well as for definition of the time of this reserve termination.

PCCS system is a complicated terminal control system and can be implemented as an autonomous system as well as with application of on-board flight computer of LV control system.

The propellant-consumption control system is applied on launch vehicles of different types. At disturbed modes of LV flight the process of propellant consumption is subjected to influence of incidental disturbances such as inaccuracies of tanks filling, spreads of engines' thrust specific impulse, aerodynamic parameters of LV etc.

Taking into account the above-mentioned factors, it is required to reserve certain warranty backup of fuel in each tank of LV in addition to operative reserve of propellant that is completely consumed in calculating nominal conditions of injection. The values of LV warranty propellant backup that is used for compensation of random disturbances can achieve 5% from the mass of operative reserve of propellants. The quantity of such "unused" fuel backup can be considerably decreased up to acceptable level (which does not exceed 0,3-0,5% from the mass of propellant operative reserve) by applying propellant consumption control system on LV.

FILLING MONITORING SYSTEM (FMS)

  • Development, testing anddesign supervision of FMSelements manufacturing;
  • Development and testing ofFMS program-algorithmsoftware;
  • Providing FMS componentsmanufacturing.

The FMS operates during LV pre-launch processing and aimed at ensuring and maintaining required volume of underfilling in LV first stage propellant tanks at the moment of oxidizer replenishment termination and fuel filling termination, as well as at monitoring of submerging of helium bottles of the first stage tanks pressurization system into liquid oxygen.
